In addition, image and text does not match with the nssrid and edf files. Please refer to image. you can considershhs1-200001_filtered_data, shhs1-200002_filtered_data and shhs1-200003_filtered_data.
Thanks in advance
I am researching for an issue on apnea cases.
My question is: Is that possible to diagnose apnea basically from the SaO2- SpO2 values only ? By this, we will figure out if there are reasonable results and make people more comfortable to get apnea treatment from their houses, especially whom are disabled.
I use the polysomnography .edf raw values, filter Time-SaO2 with EDF browser and import to MS SQL.
In MS SQL I run a query code and calculate the oxygen desaturation during all time which is appoximately 8,5 hours for each, around 30.000 secs.
I focus on the AHI and RDI basically. As I know shortly, RDI = AHI + Arousals .
When I compare the real study results ( lets consider shhs1-200041_filtered_data ), non-apnea results generally match but existing-apnea results and my own results do not seem mathcing.
I wonder, is the approach has something to add, modify or change ? Can I get some reasonable and undestandable results with this methodology.
Beside, I can share the sql query code and results if anyone wants ?
I really appreciate to hear from experts as you.
